Good Energy

Due to depletion of coal and other natural fuel there is an urgent need to find eco-friendly and workable technology for alternate energy. Microbial fuel cells is considered as assuringmethod to extract energy from various sources of wastewater and to generate electricity. But, due to practical limits, MFCs are still unsuitable to meet high power demands. Since wastewater contains several contaminants including organic substances, therefore, generation of electric energy from wastewater using MFC can offer an alternate solution for electricity issue as well as to reduce environmental pollution. Microbial fuel cells harvest electrical energy from wastewater with the help of microorganisms present within the wastewater. The energy confined in organic matter converted in to useful electric current. In Microbial Fuel Cell electrons from the microorganisms transfer from a reduced electron donor to an electron acceptor at a higher electrochemical potential. The study highlights that wastewater with high organic content found to be more effective and it also gives good energy production. If the same concept implemented in large scale it can help in achieving sustainable development and it helps in achieving 3R formula in the process of wastewater treatment.

Environmental Friendly

Microbial fuel cells (MFCs) are regarded as a promising and environmental friendly method for wastewater treatment and bio-production. The output power of a single cell is inadequate to drive loads directly. Microbial fuel cells stacked in serials will promote bio-production or bioremediation and the voltage of the MFCs can be scaled up by connecting the cells in serials, whereas voltage reversal may emerge in this case. The causes for reversing polarity of MFCs have received great attention in recent years. This paper designs a power management circuit for microbial fuel cell, studies the mechanisms of voltage reversal and the approaches to solve the problem.

ABSTRACT The ability of Pelobacter carbinolicus to oxidize electron donors with electron transfer to the anodes of microbial fuel cells was evaluated because microorganisms closely related to Pelobacter species are generally abundant on the anodes of microbial fuel cells harvesting electricity from aquatic sediments. P. carbinolicus could not produce current in a microbial fuel cell with electron donors which support Fe(III) oxide reduction by this organism. Current was produced using a coculture of P. carbinolicus and Geobacter sulfurreducens with ethanol as the fuel. Ethanol consumption was associated with the transitory accumulation of acetate and hydrogen. G. sulfurreducens alone could not metabolize ethanol, suggesting that P. carbinolicus grew in the fuel cell by converting ethanol to hydrogen and acetate, which G. sulfurreducens oxidized with electron transfer to the anode. Up to 83% of the electrons available in ethanol were recovered as electricity and in the metabolic intermediate acetate. Hydrogen consumption by G. sulfurreducens was important for ethanol metabolism by P. carbinolicus. Confocal microscopy and analysis of 16S rRNA genes revealed that half of the cells growing on the anode surface were P. carbinolicus, but there was a nearly equal number of planktonic cells of P. carbinolicus. In contrast, G. sulfurreducens was primarily attached to the anode. P. carbinolicus represents the first Fe(III) oxide-reducing microorganism found to be unable to produce current in a microbial fuel cell, providing the first suggestion that the mechanisms for extracellular electron transfer to Fe(III) oxides and fuel cell anodes may be different.

Exchange Membrane

Proton exchange membrane is an important factor affecting the power generation capacity and water purification effect of microbial fuel cells. The performance of microbial fuel cells can be improved by modifying the proton exchange membrane by some suitable method. Microbial fuel cells with membranes modified by SiO2/PVDF (polyvinylidene difluoride), sulfonated PVDF and polymerized MMA (methyl methacrylate) electrolyte were tested and their power generation capacity and water purification effect were compared. The experimental results show that the three membrane modification methods can improve the power generation capacity and water purification effect of microbial fuel cells to some extent. Among them, the microbial fuel cell with the polymerized MMA modified membrane showed the best performance, in which the output voltage was 39.52 mV, and the electricity production current density was 18.82 mA/m2, which was 2224% higher than that of microbial fuel cell with the conventional Nafion membrane; and the COD (chemical oxygen demand) removal rate was 54.8%, which was 72.9% higher than that of microbial fuel cell with the conventional Nafion membrane. Modifying the membrane with the polymerized MMA is a very effective way to improve the performance of microbial fuel cells.

Microbial Fuel Cells (MFC) are robust devices capable of taping biological energy, converting sugars into potential sources of energy. Persistent efforts are directed towards increasing power output. However, they have not been researched to the extent of making them competitive with chemical fuel cells. The power generated in a dual-chamber MFC using neutral red (NR) as the electron mediator has been previously shown to be 152.4 mW/m2 at 412.5 mA/m2 of current density. In the present work we show that Pt thin film coated carbon paper as electrodes increase the performance of a microbial fuel cell compared to conventionally employed electrodes. The results obtained using E. coli based microbial fuel cell with methylene blue and neutral red as the electron mediator, potassium ferricyanide in the cathode compartment were systematically studied and the results obtained with Pt thin film coated over carbon paper as electrodes were compared with that of graphite electrodes. Platinum coated carbon electrodes were found to be better over the previously used for microbial fuel cells and at the same time are cheaper than the preferred pure platinum electrodes.
